摘要
QM/MM studies of the hydrolysis of a beta-lactam antibiotic molecule (biapenem) catalyzed by a monozinc,beta-lactamase (CphA) have revealed the complete reaction mechanism and shown that an experimentally determined enzyme-intermediate complex is a stable intermediate or product in a minor pathway.
